3. MCU Operating Modes
Modes 1 to 4 are externally expanded modes that enable access to external memory and peripheral
devices and disable access to the on-chip ROM. Modes 1 and 2 support a maximum address space
of 1 Mbyte. Modes 3 and 4 support a maximum address space of 16 Mbytes.
The H8/3008 can be used only in modes 1 to 4. The inputs at the mode pins must select one of
these four modes. The inputs at the mode pins must not be changed during operation. Set the reset
state before changing the inputs at these pins.
3.1.2
The H8/3008 has a mode control register (MDCR) that indicates the inputs at the mode pins (MD

Note:
3.2
MDCR is an 8-bit read-only register that indicates the current operating mode of the H8/3008.
Bits 7 and 6—Reserved: These bits can not be modified and are always read as 1.
Bits 5 to 3—Reserved: These bits can not be modified and are always read as 0.
Bits 2 to 0—Mode Select 2 to 0 (MDS2 to MDS0): These bits indicate the logic levels at pins
